SPECIFICATION forming part of Letters Patent No. 343,432, dated `Tune 8, 1886.

.Application filed February 25, 1886. Serial No. 193,226. (No model.)

T0 all whom it may concern.-

Beit known that we, PERRY BEIT'roN and FRANK TRUEsDALE, citizens of the United States, residing at South Charleston, in the county of Clark and State of Ohio, have invented a new and useful Improvement in Carpet-Stretchers, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to an improvement in carpetstretchers; and it consists in the peculiar construction and combination of parts, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is aside'elevation of ourinvention. Fig. 2 is a top plan view of the same, partly in horizontal section. Fig. 3 is a detailview of one of the reversible heads.

A represents a base or platform,which is provided on its upper side with parallel arms B, which extend vertically from the base, and are arranged at asuitable distance apart.

C represents a pair vof extensible stretcherrods, which are arranged side by side between the arms B, and resting on the base A, one Yof the said rods being provided on one side with a longitudinal groove, C', and the other having a longitudinal tongue, C2, on its opposing face or side, which engages the groove C. The upper sides of the extensible rods are provided with ratchet-teeth C3.

D represents a pivotalbolt that connects th'e arms B, above the extensible rods, and on this bolt are pivoteddetents E, which extend in opposite directions from the bolt, and engage with the ratchet teeth of the extensible stretcher-rods. A similar pivotal bolt, G, connects the upper ends of the arms B, and on the said bolt is pivoted a hand lever, H, which has its lower end bifurcated, and in which `bifurcated lower end are pivoted two gravitypawls, I, which extend in opposite directions from the lower end of the hand-lever, and also engage with the ratchet-teeth of the extensible rods. By this construction it willbe readily understood that by moving the upper end ot` the hand-lever back and forth the pawls I will cause the rods C to move outwardly in oppo site directions from the base A.

From the outer ends of the rods C project dowel-pins K, on which are secured removable and reversible stretcher-heads L. These stretcher-heads are provided on one side with projecting hook-points M, for engaging with the carpet near the selvage edges thereof, when it is to be stretched crosswise on the ioor. On the opposite side on each stretcher-head is arranged a clamp, N, which is secured on the ends of the transverse bar, forming the head, by means of engaging pivoted links O, with whichv the bar N is provided. When the carof each strip or width are clamped between the bars N and the heads,and the latter are secured on theends of thestretcherrods,with the clamp bars N downward. By thus clamping the raw edges of the ends of the widths of carpet between the heads and the clamping-bars, they are prevented fromvbeing unraveled or injured when the carpet is stretchedlengthwise,which would result if the hooks on the opposite sides of the heads were used to engage near the raw edges of the carpet, as will be very readily understood. As the bars C are being moved outwardly in opposite directions, by working the hand-lever, as hereinbefore described, the detents E engage with the ratchet-teeth of the extensible bars and prevent them from slipping rearwardly, as the hand-lever is reversed in order to cause the pawls I to take a new hold. The reversible heads are secured on the outer ends of the stretcher-bars in either position by means of suitable hooks, P.

Ve are aware that it has been heretofore proposed to construct a carpet-stretcher having extensible ratchet-bars movable in opposite directions, detents engaging the said bars, and a separate pivoted handlever for each ratchet-bar, and having an engagingdog, and this construction we disclaim.

Having described our invention, we claiml. The combination, in a carpet-stretcher, of the stretcher-rods having the ratchet-teeth on their upper sides, the'pivoted detents E, engaging with the said ratchet-teeth, and the pivoted hand-lever having the pivoted pawls I, extending inl opposite directions, for engaging with the ratchet-teeth of the stretcherrods, and moving the latter outwardly in opposite directions alternately when the handlever is operated, substantially as described.
